A SMALL amount of pressure, YES, but a LOT of pressure, NO.

Our pumps are designed so that if something restricts the line, the impeller will just sit there and thurn water. In other pumps which are designed for high pressure systems, if the exit is blocked, the pump will either: burn out due to extreme stress, or cause an impeller to fracture or pump casing to crack, OR be releaved by a releif valve.

ONLY systems designed for pressure have to worry about these problems. (such as in hydrolic systems)

Remember that you can create pressure by forcing more volume into a smaller space but in our setups, its only possible to go up the our pumps rated head pressure.

Head Pressure = NO resistance; how much water can you force up that outlet with nothing attached.
